External exposures impact novice vitreoretinal surgeons’ performance

Posted on September 21, 2021

Alcohol was found to diminish surgical performance whereas propranolol was found to improve performance in novice vitreoretinal surgeons, according to a study.

In this prospective, self-controlled, cross-sectional study, the surgical performance of 15 vitreoretinal fellows with <2 years of experience using a simulator was assessed after various external exposures, including:

Day 1: placebo or caffeine (2.5 and 5 mg/kg)

Day 2: placebo or propranolol (0.2 and 0.6 mg/kg)

Day 3: baseline simulation, breathalyzer reading of 0.06% to 0.10% and 0.11% to 0.15% blood alcohol concentration

Day 4: baseline simulation, push-up sets with 50% and 85% repetition maximum

Day 5: 3-hour sleep deprivation

After increasing alcohol exposure, surgical performance was found to worsen. After propranolol exposure, performance was found to improve.  Caffeine (2.5 mg/kg) was negatively associated with dexterity. Short-term exercise and acute sleep deprivation were not found to change performance.
